The Swans are bracing themselves for a formal offer from Liverpool for top scorer Bony after Brendan Rodgers was made aware of a £19m release clause in the striker's Liberty contract.

And with Michu set to join Napoli on loan following his pleas to quit British football, Garry Monk could be about to lose two of the biggest name from his squad a month before the start of the new Premier League season.

But the rookie boss is determined to strengthen his options and has made a move for Argentina's World Cup centre-back Federico Fernandez.

Fernandez, 25, has played in four of the South American's games in Brazil en route to the final against Germany at Rio's Maracana.

Long-standing interest

But he has been eyed up by Swansea for more than a year as they kept a check on his growing reputation and increasing frustration at a lack of game time at Napoli.

Swansea had been biding their time over a potential move with Monk knowing he has to move men out before bringing too many more in.

But having opened negotiations with the Serie A giants over Michu's move, Swansea are thought to have seized the initiative by making a move for Fernandez.

Swansea have accepted Michu will and needs to move on given his growing disillusionment at the Liberty but the club were keen for it to be on a permanent basis, Napoli only wanting to agree to a 12-month loan deal in the first instance.

But Fernandez's involvement could suit all parties and tick Monk's box for extra defensive options. Swansea had lined up Bosnia's Ferencvaros star Muhamed Besic but were waiting to assess their options before pushing ahead, something Everton could take advantage of.

Swansea are expected to wrap-up a £4m deal for Ecuador winger Jefferson Montero shortly while will continue to attempt to push out the unwanted Jose Canas, Alejandro Pozuelo while Pablo Hernandez is still being eyed up by Spanish clubs after making it clear he wants to move this summer.

Monk is likely to be told he could use the cash from any Bony sale to further boost his numbers, although will not be under huge pressure in terms of a striker given the early summer swoop for Bafetimbi Gomis.

Swansea will now wait to see whether Liverpool want to turn their interest into a serious offer over the coming days, with Bony expected to join up with the rest of the Swans squad in Chicago by the end of the week.
